WEBCON Inc.Tissue Roll Winding
Winding a Uniform Roll in Converting Winders
OUR DESIGN EXPERTISE
Our design expertise covers the entire range of a tissue winding steps to designing a complete winding line for tissue or other specific needs. The range of materials to be wound includes tissue, towel, non woven, gauze, laminates, wipers, etc. We specialize in the Design of Cams, especially for the winding process cams for center as well as surface winders; and cams for reciprocating motions involved in wrappers, case packers and bundlers.
Starting from concept, we engage in prototype development, followed by engineering, design (CAD) and manufacture of the complete production machine.
In addition to the machines designed and manufactured according to the patents listed below, other machines include
Complete winding line for Kitchen Towel with a proprietary winder and a wrapper;
Winders for specialty items such as absorbent pads, gauzes and non wovens.
Single roll paper wrapper rated at 105 rolls per minute.
DESIGN OF WINDING CAMS
Given the product specifications, compute the profile of the winding cam, as NC code for milling the metal cam. Alternatiely, convert the profile into a table of values for a soft cam.
Given the winder geometry and product specifications, develop the kinematic formulas to wind a perfect Archimedean Spiral. In case of center winders, the formulation includes contributions of turret swing and indexing, and the epicyclic action of the serpentine belt.
In the case of surface winders, it involves the contribution due to moving contact points in the winding nest.
"MW150H" calculates the winding table and N-C code for creating the cone pulley cam.
"MW150S" generates the winding table suitable for any electronic drive.
"MW200H" calculates the winding table and N-C code for steel cam for older 200 winders.
"MW200S" generates the winding table for soft cam for Series 200 and later winders.
"SURFAC" calculates the winding table for Diatrol cam controlled Perini Winders
"DIATRL" designs the Diatrol cam and develops the N-C milling code
The above programs are modified to handle alternative geometries.
